• What is Stress?

Have you ever found yourself in a situation where your to-do list seems endless, deadlines are fast approaching and you find yourself saying ‘Eek! I feel stressed!’? But what is stress really, and how does it affect us?

Firstly, let’s debunk one myth: stress is not necessarily a ‘bad’ thing. Without this brilliant ability to feel stress, humankind wouldn’t have survived. Our cavemen ancestors, for example, used the onset of stress to alert them to a potential danger, such as a sabre-toothed tiger.

Stress is primarily a physical response. When stressed, the body thinks it is under attack and switches to ‘fight or flight’ mode, releasing a complex mix of hormones and chemicals such as adrenaline, cortisol and norepinephrine to prepare the body for physical action. This causes a number of reactions, from blood being diverted to muscles to shutting down unnecessary bodily functions such as digestion.

Through the release of hormones such as adrenaline, cortisol and norepinephrine, the caveman gained a rush of energy, which prepared him to either fight the tiger or run away. That heart pounding, fast breathing sensation is the adrenaline; as well as a boost of energy, it enables us to focus our attention so we can quickly respond to the situation.

In the modern world, the ‘fight or flight’ mode can still help us survive dangerous situations, such as reacting swiftly to a person running in front of our car by slamming on the brakes.

The challenge is when our body goes into a state of stress in inappropriate situations. When blood flow is going only to the most important muscles needed to fight or flee, brain function is minimised. This can lead to an inability to ‘think straight’; a state that is a great hindrance in both our work and home lives. If we are kept in a state of stress for long periods, it can be detrimental to our health.  The results of having elevated cortisol levels can be an increase in sugar and blood pressure levels, and a decrease in libido.

When your body goes into a state of stress, we may feel agitated and aggressive towards others; this can be due to our bodies’ natural reaction being “fight”. This can be a helpful reaction to ward off predators, but in unnecessary situations, it can negatively affect relationships and ruin reputations.

Some of us avoid our stressors, removing ourselves from the situation instead of tackling it. This can be a sign of the “flight” survival instinct; a function that can save our lives if we find ourselves in dangerous surroundings. However, in everyday life, this natural instinct can lead to a stressful situation escalating, and increase our stress levels when we realise that the stressor isn’t going away and we need to face it.

Unknown by many, there is a third mode that stress can cause; freeze. For some people, becoming stressed sets the stage for ‘dysregulation’. The energy mobilized by the perceived threat gets “locked” into the nervous system and we ‘freeze’. This  response sometimes reveals itself when we breathe. Holding our breath and shallow breathing are both forms of freeze. The occasional deep sigh is the nervous system catching up on its oxygen intake.
